I hate to say this but I just sit down and write. Sometimes it’s even in between reading something else at the time that’s giving me inspiration, like my research books on the Tarot, or just whatever I’m reading at the time. Of if I have a theme, like with the weekly challenges.
Take for instance this weekend I want to write a tea blessing for myself since I need to do a thing to catch up on the Water Element badge. I’ve been thinking of what I want for myself for the day, what blessings I would ask for like health, prosperity, courage. Whatever it is you want. Then I just take the time to sit down and write it out. The rhyming dictionary helps a lot!
Hope this helps you out! Good luck writing!
